Fixing the "parsing rules with idents later declared as keywords" problem.
The fix was actually elementary. The lexer comes with a function to
compare parsed tokens against tokens of the parsing rules. It is
enough to have this function considering an ident in a parsing rule to
be equal to the corresponding string parsed as a keyword.
